Graphene Kirigami And Its Use In Biocompatible Strain Sensor, Erik Vyhmeister
Graphene Kirigami And Its Use In Biocompatible Strain Sensor, Erik Vyhmeister
Honors Theses
Graphene's large fracture strain (>30%), chemical inertness, and piezoresistive nature make it well suited for use as a biocompatible strain sensor. A rectangular multilayer strucutre with graphene as its operative component was designed. It consists of a bottom layer of SU-8, a center layer of graphene, and a top layer of SU-8 and gold, with gold acting as the electrical contact. Kirigami-style patterning is applied via photolithography and oxygen plasma etching, allowing for a greater fracture strain. Additionally, the kirigami affects the stress concentraton in the graphene, affecting its piezoresistive gauge factor. The complete (patterned) structure exhibited a fracture …

Evaluating The Efficacy Of Educational Games In Promoting Interest And Understanding Of Gravitational Wave Physics, Jonathan Wheeler
Honors Theses
The LIGO Scientific Collaboration Education and Public Outreach group seeks to ameliorate the lack of public understanding of gravitational wave physics. One such effort is Black Hole Pong, a remake of the 1972 arcade classic developed by researchers at University of Birmingham, UK. Black Hole Pong differs from other educational games in that it stretches the laws of physics to make the user experience more exciting. Another effort has been my own work in developing a game called Chickens in Space where players can create mass, which coalesces and eventually forms black holes, which serve as obstacles to the players. …
